Commit "ARM: i.MX IOMUX-V3 replace struct pad_desc with bitmapped cookie"
(b705cb4d42e95a4a43a8945571c8613e71526c3d) introduced a typo which was

The following patch is a first step to convert the 'struct pad_desc'
to a bitmapped cookie to facilitate adding platform specific pullup or
drive strength definitions to existing pad definitions without need to
rewrite the complete pad def.
The patch wraps 'struct pad_desc' in an opaque data type and
introduces macros to access the individual members.
This patch does not constitute any functional change!

The PLLC2 clock was utilizing the same sort of enable/disable without
regard to usecount approach that the FSIDIV clock was when being used as
a PLL pass-through. This forces the enable/disable through the clock
framework, which now prevents the clock from being ripped out or modified
underneath users that have an existing handle on it.

init_mm used at kernel/sched.c:idle_task_exit() has spin_lock
(init_mm.context.id_lock) that is not initialized when spin_lock/unlock
is called at an ARM machine. Note that mm_struct.context.id_lock is
usually initialized except for the instance of init_mm at
linux/arch/arm/mm/context.c
Not initializing this spinlock incurs "BUG: pinlock bad magic"
warning when spinlock debug is enabled. We have observed such
instances when testing PM in S5PC210 machines.

We now:
* check for a v3 controller before setting 8-bit bus width
* offer a callback for platform code to switch to 8-bit mode, which
allows non-v3 controllers to support it
* rely on mmc->caps |= MMC_CAP_8_BIT_DATA; in platform code to specify
that the board designers have indeed brought out all the pins for
8-bit to the slot.
We were previously relying only on whether the *controller* supported
8-bit, which doesn't tell us anything about the pin configuration in
the board design.
This fixes the MMC card regression reported by Maxim Levitsky here:
http://thread.gmane.org/gmane.linux.kernel.mmc/4336
by no longer assuming that 8-bit works by default.

The issue is that we don't set IO permissions for the Linux kernel early enough.
The call sequence used to be:
xen_start_kernel()
x86_init.oem.arch_setup = xen_setup_arch;
setup_arch:
- early_cpu_init
- early_init_amd
- read_pci_config
- x86_init.oem.arch_setup [ xen_arch_setup ]
- set IO permissions.
We need to set the IO permissions earlier on, which this patch does.

The .stack section doesn't contain any contents, and doesn't require
initialization either. Rather than marking the output section with
'NOLOAD' but still having it exist in the object files, mark it with
%nobits which avoids the assembler marking the section with 'CONTENTS'.

Commit 8b592783 added a Thumb-2 variant of usracc which, when it is
called with \rept=2, calls usraccoff once with an offset of 0 and
secondly with a hard-coded offset of 4 in order to avoid incrementing
the pointer again. If \inc != 4 then we will store the data to the wrong
offset from \ptr. Luckily, the only caller that passes \rept=2 to this
function is __clear_user so we haven't been actively corrupting user data.
This patch fixes usracc to pass \inc instead of #4 to usraccoff
when it is called a second time.

The current implementation of sched_clock() for the Nomadik
family is based on the clock source that will wrap around without
any compensation. Currently on the Ux500 after 1030 seconds.
Utilize cnt32_to_63 to expand the sched_clock() counter to 63
bits and introduce a keepwarm() timer to assure that sched clock
and this cnt32_to_63 is called atleast once every half period.
When I print out the actual wrap-around time, and using
a year (3600*24*365 seconds) as minumum wrap limit I get an
actual wrap-around of:
sched_clock: using 55 bits @ 8333125 Hz wrap in 416 days

Commit 7c63984b86 (ARM: do not define VMALLOC_END relative to PAGE_OFFSET)
changed VMALLOC_END to be an explicit value. Before this, it was
relative to PAGE_OFFSET and therefore converted to unsigned long
as PAGE_OFFSET is an unsigned long. This introduced the following
build warning. Fix this by changing the explicit defines of
VMALLOC_END to be unsigned long.
